just put a skunk 2 manifold on my da9 it bogs in the low rpm's but raps it up pretty quick past 5k, there is no vaccum leaks either. am i getting to much air... if so what can i get to curve it in an inexpensive way... thanks in advance.

 

just double check all your vaccum lines, what's your idle at ? I've seen other manifolds like the JG edelbrock have low RPM problems becuase of the plenum but never the SK2

 

this probably doesnt have to do with your problem but the low end with the skunk im is less power than the stock im
